About

Serving the greater Portland area for almost 20 years - Antoinette Antique and Estate Jewelry features Portland’s largest collection of vintage and antique engagement rings with ethical old cut diamonds, as well as fine jewelry ranging from the 1800s to the 1950s, with something beautiful for every taste and budget.

While we specialize in old antique, hand-cut diamonds, you will also find expertly-selected, exquisite pieces with colored gemstones. Whether you are interested in a specific period, such as Victorian, Edwardian, Art Nouveau, Art Deco or Retro, have your heart set on a hard-to-find antique diamond like an old hand cut rose cut, or have no idea what you’re looking for and want to try everything on, we are here to help.

Antoinette (yes, that’s her real name!) holds her Graduate Gemologist degree from America’s most highly regarded gemological institute, GIA. A dozen years of classes from the jewelry appraisers you’ve seen on the Antiques Roadshows, along with her GG, have given her a depth of expertise few others can claim.

Antoinette is a GIA Graduate Gemologist
Member of NAJA (National Association of Jewelry Appraisers)
